Abstract

UN TRANSCONDUCTOR ELECTROMECANICO BIESTABLE ES DESCUBIERTO TENIENDO UNA ARMADURA (3, 20) RECIPROCABLE ENTRE LAS POSICIONES PRIMERA Y SEGUNDA, UN IMAN PERMANENTE (26) DE CERROJO DISPUESTO PARA MANTENER LA ARMADURA (3, 20) EN LAS RESPECTIVAS POSICIONES, Y UN ARREGLO DE REPULSION ELECTROMAGNETICA (13, 15) OPERABLE CUANDO ACTIVAMOS A DESALOJAR LA ARMADURA (3, 20) DESDE LA POSICION EN LA CUAL LA ARMADURA SE MANTENIA Y CAUSANDOLA A MOVERSE A LA OTRA POSICION. EN LA PERSONIFICACION PREFERIDA, DE TRANSCONDUCTOR TOMA LA FORMA DE UN MECANISMO DE VALVULA CONTROLABLE ELECTRONICAMENTE PARA USAR EN UNA MAQUINA DE COMBUSTION INTERNA Y TIENE UNA VALVULA DE MAQUINA (1) CON UN VASTAGO DE VALVULA ALARGADO (17) CON EL ARREGLO DE REPULSION ELECTROMAGNETICA (13, 15) PARA CAUSAR A LA VALVULA A MOVERSE EN LA DIRECCION DE LA ELONGACION DEL VASTAGO ENTRE LAS POSICIONES DE VALVULA ABIERTA Y VALVULA CERRADA. UN ARREGLO PARA DECELERAR LA VALVULA ASI COMO LAS VALVULAS CERCANAS A LAS RESPECTIVAS POSICIONES DE VALVULAABIERTA Y VALVULA CERRADA INCLUYE AL MENOS DOS ARREGLOS AMORTIGUADORES SEPARADOS (4, 21, 35, 37) CONJUNTAMENTE EFECTIVA AL MOVIMIENTO DE LA VALVULA LENTA ASI COMO LA VALVULA QUE SE CIERRA A DICHA POSICION. LA AMORTIGUACION DEBE INCLUIR ROTURA DINAMICA Y RECUPERACION DE ENERGIA. EL MECANISMO DEBE TAMBIEN INCLUIR UN ALOJAMIENTO (23) AL MENOS PARCIALMENTE ALREDEDOR DEL VASTAGO DE LA VALVULA Y UN ARREGLO (49) PARA LA CIRCULACION DE UN FLUIDO REFRIGERANTE LIQUIDO DE LA MAQUINA POR UNA PARTE DEL ALOJAMIENTO
